Abstract: [Technical Problem] An object is to provide a heat insulation coat having a novel form/structure different from conventional ones. [Solution to Problem] The present invention provides a heat insulation coat having a spongy body that is composed of non-linear pores and a skeleton incorporating the pores. The skeleton is an amorphous body comprising Al, Si, O, and impurities and has an amorphous peak specified by X-ray diffraction analysis at a position of 3.5 ? or more as the lattice spacing. The heat insulation coat has an apparent density of 1 g/cm3 or less, a volumetric specific heat of 1,000 kJ/m3·K or less, and a thermal conductivity of 2 W/m·K or less. The spongy body is obtained through forming a base layer, such as by thermal-spraying an aluminum alloy that contains a large amount of Si, and performing an anodizing process by AC/DC superimposition energization on the base layer. The amount of Si in the base layer may be, for example, 16 to 48 mass % with respect to the alloy as a whole.

Abstract: This invention realizes an editing system and control method thereof capable of significantly improving working efficiency of editing work. A proxy editing terminal device creates an EDL with low-resolution video/audio data, resulting in reducing time to create the EDL. Further, the low-resolution video/audio data and high-resolution video/audio data having the same contents and different resolutions are previously stored, so that the creation of a final edit list with the high-resolution video/audio data based on the EDL can be started in a short time after the EDL is created with the low-resolution video/audio data. Thus working efficiency of the editing work can be significantly reduced with reducing time to create the EDL and the final edit list.
